public static function likecheck($str, $searchTerm) {
    $searchTerm = strtolower($searchTerm);
    $str = strtolower($str);
    $pos = strpos($str, $searchTerm);
    if ($pos === false)
        return false;
    else
        return true;
}
it works fine to match any single word from $str
$found = App\Helper::likecheck('Developers are very good','very');
if($found){
    echo 'ok';
}
But I want to check by giving more words separated by commas, if any of the words is found then return true
LIKE:
$found = App\Helper::likecheck('Developers are very good','very, good, gentle');
if($found){
    echo 'found';
}
But it does not as it can check only one word.
